iggire 11 is a side elevation of a handcontrolled operating mechanism for the locky 1ng device, the dashboard being shown in 0n the chassis 20 of an automobile or other vehicle is mounted the usual motor 21 enclosed within a hood 22 adapted toA be locked to the chassis by interior locking devices 23, preferably one on each side as` 1, 2, 3, 4 and 5, but alike shown'in Figures in construction so but one in detail. hood 22 is secured that it su ces to describe On the inner face of the guideway 26 l.attached to an angle iron 27 secured to the chassis 20 and` extending lengthwise on the inner' face of the corresponding side of the hood 22 thus forming an abutment for the corresponding side of the hood, as will be readily understood by reference to Figures 3, 4 and 5. In order to hold the corresponding side of the hood 22 against outward movement use is made of catches 28 riveted orotherwise securedv to the inner face of-each side of the hood 22 and adapted to straddle the vertical member of the corresponding angle iron 27 (see Fig- 25 is provided with a hea'd 30 having a rod 31 parallel to the bolt 25 and mounted to slide in the bearing 26, and on this rod 31 is coiled a spring 32 interposed between the bearing 26 and the head 3() to normally hold the bolt with the keeper 24. The sliding movement of the rod 31 is limited by a nut 33 screwing on the threaded end 34 of the rod 31. The nut 33 is adapted to abut against the bearing 26 at the time the bolt 25 is out of engagement with the keeper 24. A jam nut screwing on the threaded end 34 of the rod 31 serves to lock the stop nut 33 in the adjusted position. The head 30 of the bolt 25 is connected by a universal joint 36 with a rod 37 pivotally connected with a pivot 38 held on a link 39 mounted to swing on a pivot 40 held on a bracket 41 adjustably secured by a bolt 42 to a bracket 43 fastened by bolts or other fastening devices 44 to the an enlarged sectional side ele-H.

corresponding auele iron il. The bolt k3 extends through an elongated slot l5 tormed in the bracket 4l to allow ot' adjusting` the latter transversely on the bracket 423 to uiovc. the link 39 into the desired position. The pivot 38 ot' the lett-hand locking:r device tor the. hood is pivotally connected with a rod mounted tf' slide in a bearing 5l attached to the dashboard 52. The rod 50 is provided with au inner section :'ipivotally connected with the pivot 3S. and in this Section 53 screws the threaded end :it ot' a section 55 on which is mounted to slide a tubular section 5G mounted to sl idc in the bea r ingr 5l and terminating in a head adapted to be pressed by the foot ot the operator in charge ot' the automobile. A. nut 5S screws on the inner end ol` the screw 5G and normally abuts against the inner end ot the bearing; l.. A spring` 30 is interposed between the nut and the section 57i to provide a vielding connection between the sections 55,65. Thus when the operator presses the head with the `toot the-spring 59 "is compressed but compression is limited by the head (30 olt a screw (Si, screwing` in the end oi' the section 5:3 and against which is adapted to abut the head 5T (see Figure 6).

Instead of actuating the rod 50 by toot use may bc made ot a h:nutcontrolled lever (-35 Figure ll) tulcrunied on a bracket G6 attached to the dashboard The lever is pivotally connected with the head 57 ot' the rod 50 and hence when the lever 65 is swung' rear ard by the operator in charge, ot the automobile the. rod 50 is pushed torward the same as if the head 57 were pushed torward by the toot of the operator.

Within the hood 2Q and'in the upper rear port-ion thereof is arranged an extensible rock shaft journaled in-adjustable bearings '71 attached to the 'forward face ot the dashboard The rock shaft 70 controls a plurality of devices connected with ditlerent members ot' .the motor 2l. tor rendering the latter inoperative b v each of the said devices, As shown in the drawings. use is made ot a shut-ofi` valve T2 arranged in the pipe 73 'connecting the reservoir 74 with the carbureter 'T5 of the motor 2l. it beine' undei-stood that this valve 72 normally in open position but is moved into closed position whenever the operator presses the. rod 50 in a forward direction. lt is understood that when the valve 72 is closed the supply of the motor tuel is eut ott and hence the motor cannot be run. The i alvc 72 is provided with an arm 76 connected by a secitional lilik 77 with an arin 78 secured on the rock shaft 70 and hence when the latter is rocked on moving the rod 50 forward then the valve 72 is moved into closed position for the purpose mentioned.

. A butterfly valve 80 arranged in the pipe 81 connecting the carbureter 75 with the inlake manifold trl of the motor :il is provided with a rock shat't Si), on one outer end ot' which is secured the, usual arm connected with the usual controlling mechanism under the control ot thc operator tor moving the butterfly valve 80 into open or closed position. On the other end ot the rock shat't QS is secured an arm Slprovided with a pin S5 engaging a slot 86 formed in the tree end ot` a sectional link 87 pivotally connected with an arm S8 attached to the rock shat't T0. lt will be noticed that the buttcrlly valve 0 can be readily moved into open and closed position by the operator actuating the usual controlling mechanism without interfering with the link 8T, but when the rock shatt T0 is actuated atter the motor is stopped then the butterfly valve S0 moves into closed position by the action otI the link 8T engaging thc arm 84 thus preventing the motor "2l from being' started and run.

The rock shatt T0 is actuated trom the rod 50 and for this purpose the rock shaft T0 is provided with arms 90 each pivotally connected with a pivot 91 connected by a link D2 with the pivot 258 and hence when the rod fi() is nioved inward a rocking" movement is {riven to the rock shaft. 70 by the links 92 and the arms, 00. Vtis umlerstood that by the connection just described but one rod 5() is needed i'or actuating' the two hood loekinpy devices the rod 50 being' preferably located on the lettdiand side ot' the machine, as illustrated in Figure l Another device in the torm ol a switch is arranged within the hood Q2 'tor breaking the ignition circuit of the motor 2l thus rendering' the latter inoperative. For this purpose use is made ot' a slide 100 mounted to slide up and down in a bearing 101 attached to the forward tace ot the dashboard On this slide 100 is secured a switch bar M2 of an insulating material and carryiirc` a contact 103 adapted to engage a pair ot contacts 104 secured on a bar 105 ot insulatimfv material and secured to the forward Jface ot the dashboard The contacts 10? and lll-'l are connected by wires 100 and 10T with the spark plugs and the timer ot the ignition system ot the motor 2l. Normallyy the contacts '102% and 104 are in engagement with each other to complete the circuit ot the ignition system but when the rod 50 is moved torward and the hood lockingr device is moved into closed position and the valves T1? and 80 are moved into inoperative positions then the contact 103 is moved out ot engagement with the contact 104 to break the circuit of the ignition system. In order to do so the slide 100 is moved upward and this slide is connected with one end ot a lever 110 tulcrumed on vthe bearing 101 and pivotally connected by a link lll with the 'pivot 91. on the right-hand side of the machine. Thus when the rock shaft'() is actuated an its upward drawing movement is given to the slide 100.

The slide 11)() (see Figure 3) is provided with an aperture adapted to be engaged by a bolt 116 mounted to slide at. its forward end in a bearing 11'? attached to the dashboard 52. The bolt 116 is provided with an enlarged portion 118 mounted to slide in a tubular bearing 119 screwed or otherwise secured to the bearing 117. The forward end ot' the bolt 116 is threaded into an extension bolt 120 mounted to slide in a bear- .ing 121 adjustably mounted on the bearingr 119, the latter having` a key 122 engaging a keyway 123 Jformed in the bearing 121. ln the rear end of the bolt 120 is formed a collar 125 pressed ou by a springV 126 coiled around 'the extension bolt 12() and seated on the bearingr 12.1. The spring 126 tends to move the connected bolts 116 and 120 in a torward direction. that the bolt 116 out of engagement with the aperture 115. A brace 12T is connected with the rear end of the bearing' 121 and this brace 127 is provided with an extension brace 12S pivotally connected at 129 with the dashboard 52 to hold the bearinp` 121 in proper position.

lu order to hold the bolts 12() and 116 in locking; position. the valves T2 and SO in closed position, the bolts 25 in locking position, the Contact 103 in circuit breaking` position, and the rod 5() in forward positionl` use is made ot a locking device adapted to hold the bolts 12()` and 116 in lockingr position relative to the slide 100. l or this purpose the rear end of the extension bolt 120 is engaged by a lockinzgr arm 13o pivotally connected at its lower end by a pivot 131 with a cap piecev 132 formingr part of the bearing 121 bv`bing screwed thereon. The upper end ot the lockino' arm 130 is pivotally connected with a loe ring arm 133 adapted to engage a frame 13eL secured to the instrument board 135 otl the automobile. The lower end of this frame 131 is pivotally connected at 136 with the cap piece 132 to allow the frame 134 to fit differently iuclined instrument boards 135` ot' dill'erent makes ot automobiles. The trame 134 and the arm 133 forni parts of a permutation lock of any approved construction but preterably of the construction more fully shown and described in the Letters Patent of the United States No. 1,343,043, granted to me on June 3. 1920. The permutation lock is provided with a locking slide 140 adapted to engage the arm 133 to lock the latter in closed position. and the said locking slide 140 is controlled by tumblers 141 mounted to turn on the frame 134: and provided with the usual letters, numerals or other characters (see Figure 9) to permit of setting the tumblers to any desired combination and which combination is known only to the opera-tor in charge of the vehicle, and hence unauthorized persons cannot open the lock and release the arm 132 and conswpiently tho locking arm 130. When the operator in charge desires to start the vehicle he sets the tumblers 111 to the predetermined. coni binatiou thus unlocking' the slide 14() to re! lease the arm 133 thereby allowing the latter and the arm 131) to swing' downward into unlockingr position, indicated in dotted lines in Figure 1l). and when the arm 132 moves into this position it unlocks the connected bolts 116 and 120 and the same move rearward by the action of the sprint@r 126, and when this takes place the forward end of the bolt 116 moves out ot the aperture 115 thus releasing or unlocking the slide '166. ilVhen this takes place, the several parts within the hood return to normal positions by the actions ot the springs 32 and 5E). 1t is understood .that when thisftakes place the hood 22 is unlocked. the valves T2 and 31) move into open position, the contact 103 moves into engagement with the contact 104 thus closing the ignition circuits, and the rod 50 returnsto normal rearward posi tion.

ln order to permit ot' using the locking;r device for different types ot automobiles,

`the rock shaft 7() is preferably provided 'with telescopmg side extensions 150 having:y

keyways 1.51 (see Figure 10) engaging keys 152 formed on the shaft 76. The extensions 15() carry the several arms 73. r3 and 96. The bearings T1 for the shaft Td are made adjustable and for this purpose each bearing is provided with a. screw rod 161) (see Figure 10)held adjustable in an arm 161 b v nuts 162 and 163. The arm 161 Vis held adjustable in a bracket 165 by the use of nuts 166 and 167, and the bracket 165 is attached to the forward face of the dashboard 52. lt will be noticed that by the arrangement described the rock shatt 76 can be adjusted up or down, forward or backward, to suit conditions.
